Swinub rubbed his nose against the ground to find food. His favorite food is a fungus that grows under dead grass, but will eat anything that pleases their nose. It has one of the best senses of smell among Pokémon, so many people use it to find treasures and many companies use it to find hot springs. When they do, your hair stands on end, and often jump to indicate the place. It also seems to be based on a Topo Dorado.
